Abstract
The experimental status concerning the two new narrow states with charm-strange content is reviewed. The states have masses of 2317 and 2460 MeV, widths less than 10 MeV, isospin consistent with zero, and spin-parities consistent with being 0^+ and 1^+, respectively. Although the masses are lower than the conventional expectation, these states appear to be the j=1/2 P-wave levels of the D s system, where j is the light quark angular momentum; there may be mixing with the j=3/2 level for the 1^+ state.
